Don't worry about stiffness in Newtons - I'm just a "normal" sort of 12 stone and am on my third pair of Newtons - I swear by them; the stiffness when new wears off as the fairly thick sole thins and they mould to your foot shape really well.
I can also endorse Muel's advice about Spires - I'm on my third pair of those as well!
By the way, despite being from the same manufacturer there's a World of difference in sizing. I take a 42 or 42.5 in street shoes and the same in Spires, but 43/43.5 in Newtons.
Come to think of it I have too many shoes - if you can use a Spire in 42.5 I've a very little used pair we could negotiate a price for?
